Hypochlorous acid is an unstable compound, and one of the decomposition products is chlorine gas, \(\ce{Cl2}\) . The decomposition of the acid lowers its concentration over time. What effect will the decomposition of one-fourth of the acid have on the agreementbetween the endpoint of the titration and the equivalence point during a titration with standard sodium hydroxide?

A.
The endpoint would remain near the ideal equivalence point.
B.
The endpoint would be after the ideal equivalence point.
C.
The endpoint would be before the ideal equivalence point.
D.
It is impossible to determine.
